Add customer facing side - Send customers a link to the status of their room or text msg notification

When a customer makes a reservation, sends a link that activates on the day of their stay, so that they can see the status of their room and exactly when their room is ready.

Could be utilized in a Customer facing app (to be created) called "YourStay" or "Stay", which would allow for a catalog of customers' hotel stays and give them an app interface for this feature.
